【推荐2】The Great Wall of China is famous around the word, but not many foreign people know about the Grand Canal—a man-made waterway. It is also called Da Yunhe in China.
The Grand Canal is 1,700 kilometers long and some parts of it are more than 2,000 years old. It links (连接) the north of China with Hangzhou, a city in the southern part of the country. It’s the longest man-made waterway in the world.
People built it as a way to take grain (谷物) from China’s south to the north. In fact, it’s also a system (系统) of canals and rivers. It’s still an important part of the transport (运输) system in China.
A large number of boats use it every day to transport grain and many other things. Now China is doing new work on the Grand Canal. It is making parts of it deeper (深), so bigger boats can use it. The canal will also help to move water. There is a lot of rain in the south of the China, but not as much in the north. It will take water from the south to the north. The Grand Canal is much less famous than the Great Wall, and not many people visit it. But it’s possible to go on a travel along some of the oldest parts of the canal. Visitors can see beautiful parts of China that other visitors don’t see.

In 2020, China’s Chang’e 5 mission collected 1,731 grams of moon soil (土壤) and brought it to Earth. (A)China became the third country to collect moon soil after Russia and the United States. Up to now, a total of 44,857.7 milligrams of the soil have been given to 62 research teams in China. By studying the soil, scientists learn more about the moon’s geology (地质), weather and other things, according to the Chinese Academy of Sciences (CAS). What new findings have scientists made? Let’s have a look.
Air on the moon
In May, scientists from Nanjing University found that the soil on the moon might be useful for turning carbon dioxide (CO2) into oxygen (氧气) and fuel (燃料). The soil has some special chemicals in it. (B)These can work as catalysts (催化剂) to make oxygen with sunlight and CO2. If this really works, astronauts can turn the CO2 they breathe into oxygen. Then they can live on the moon for a longer time. The team hopes for a chance to test this system on the moon someday.
Powerful energy
(C)Helium (氦)-3 is a valuable fuel that can provide safer nuclear energy (核能). It is not radioactive (放射性的) and would not produce dangerous waste. It’s rare (稀有的) on Earth, but after studying samples of moon soil, scientists found that the moon is rich in Helium-3! According to Ouyang Ziyuan, a senior adviser to China’s lunar program and its former chief scientist, there is enough Helium-3 on the moon for all people on Earth to have clean energy for 10,000 years!
